Sorry accidentally touched the wrong key. I'm sure there's better amps but I've always enjoyed the Phase and never thought it was the POS that evidently many "audiophiles" consider it to be! Especially when ya consider it's almost 50 years old and only 1 service for a bit over $200 !!! Still powers the AMT's with no effort, and even powers my JBL SRX700 DJ speakers to Earschplittenloudenboomer levels (though it does run out of Juice before the speakers are maxed).If it sounds good to you, enjoy what ya have. If ya have a butt-load of money to chase the "best" more power to ya!
